IPC: C09D115/02
Filed: 1936-03-26
Abstract: Acetals of hydroxyalkylaryl ethers are used as softeners for chlorine-containing film-forming materials such as chlorinated rubber, polyvinyl chloride, addition products of hydrochloric acid and caoutchouc, polymeric vinyl esters from chlorine - containing acids (polyvinyl chloracetate) and after-chlorinated polyvinyl chloride or 2-chlorobutadiene-1 : 3 polymers.  After softeners, pigments, fillers or resins may also be present.  In a table, properties of varnish coatings containing chlorinated rubber, titanium dioxide, xylene and chlorinated diphenyl, dibutyl phthalate, tricresyl phosphate, and the formaldehyde acetal of phenoxyethanol or of cresoxyethanol or of b -hydroxyethyl-p-tolyl sulphide, or the acetaldehyde acetal of phenoxyethanol, are indicated.  In examples, (1) a rust-free iron plate is coated with a varnish comprising chlorinated rubber, formaldehyde acetal of cresoxyethanol, chlorinated diphenyl, red lead and a toluene-xylene mixture, and then twice lacquered with a chlorinated rubber - formaldehyde acetal of phenoxyethanol lacquer, the chlorinated rubber in both cases being replaced if desired by after-chlorinated polymerized 2-chlorobutadiene-1.3; (2) rust-free iron articles such as tubes are coated with a varnish layer comprising after - chlorinated polyvinyl chloride, formaldehyde acetals of phenoxyethanol and of b -hydroxyethyl-p-tolyl sulphide, acetaldehyde acetal of phenoxyethanol, iron oxide, ethyl acetate, butyl acetate and xylene; (3) sheet iron is coated with a composition comprising polyvinyl chloracetate, formaldehyde acetal of phenoxyethanol, tricresylphosphate, titanium dioxide, benzene, methanol, methyl acetate, butyl acetate; (4) iron articles are varnished with a composition comprising polyvinylchloride, formaldehyde acetal of phenoxyethanol, red ferric oxide, xylene, butyl acetate and cyclohexanone; (5) pine board is varnished with a composition comprising chlorinated rubber, linseed oil, cobalt naphthenate, formaldehyde acetal of phenoxyethanol, red ferric oxide, toluene and xylene.  The Provisional Specification refers in general to compositions derived from halogen-containing film-forming materials. The formaldehyde acetal of cresoxyethanol is prepared by heating sodium o-cresolate with formaldehyde di-(b -chlorethyl)-acetal. The formaldehyde acetal of phenoxyethanol, the acetaldehyde acetal of phenoxyethanol and the formaldehyde acetal of b -hydroxy-p-tolylsulphide are similarly prepared.ALSO:Acetals of hydroxyalkylaryl ethers are used as softeners for chlorine-containing filmforming materials such as chlorinated rubber, additive products of hydrochloric acid and caoutchouc and after-chlorinated polymeric 2 - chlorobutadiene - 1 : 3 - butadiene.  Other softeners, pigments, fillers or resins may also be present.  In a table, properties of varnish coatings containing chlorinated rubber, titanium dioxide, xylene, chlorinated diphenyl, dibutyl phthalate, tricresyl phosphate, and the formaldehyde acetal of phenoxyethanol or of cresoxyethanol or of b -hydroxyethyl-p-tolyl sulphide, or the acetaldehyde acetal of phenoxyethanol, are indicated.  In examples: (1) a rust-free iron plate is coated with a varnish comprising chlorinated rubber, formaldehyde acetal of cresoxyethanol, chlorinated diphenyl, red lead, toluene and xylene, and then twice lacquered with a chlorinated rubber lacquer containing formaldehyde acetal of phenoxyethanol--the chlorinated rubber in both cases being replaceable by after-chlorinated polymeric 2-chlorobutadiene-1 : 3; (5) pine board is varnished with a composition comprising chlorinated rubber, linseed oil, cobalt naphthenate, red ferric oxide, toluene and xylene.
